Drink a frozen margarita at Mariano's

We’re not saying this is the finest frozen margarita in Dallas. But, according to legend, Tex-Mex restaurateur Mariano Martinez invented the popular frosty libation back in the 1970s. So, it’s the first. Heck, the Smithsonian even inducted Mariano’s frozen margarita machine into its hallowed halls in 2005. Fine. Who are we to argue with the Smithsonian? Go indulge.
